Millions and millions of barrels of oil, coal, and natural gases are being pumped out of the ground on a daily basis. These fuels are being used to heat homes, run machines, and take people from place to place. It has become a part of everyday living; just as essential as food and water. The more resources that is being pumped, the more people want it. Society has an insatiable thirst for this form of energy that is unyielding. It is a never ending cycle of supply and demand. The demand is high, but the supply is limited. One day the earth will be sucked dry of all its resources, yet people will continue to demand. What will happen then? What will take place of the current resources? Due to this crisis, finding alternative sources of energy has already gone underway and is advancing rapidly. The functional concept of alternative resources can be best explained through solar energy, wind energy, hydropower energy.
The sun shines and gives warmth upon the earth on a daily basis. The sun rises in the east and sets in the west continuously, therefore making sunlight a very reliable source for renewable energy. In order to convert this sunlight into usable energy, a solar energy collector transforms the absorbed light into heat, which is collected through a heat transfer fluid (HTF) and then passed on to a heat storage tank (Henkel, pars.2). Heat transfer fluid is a liquid that absorbs the heat from one object to another. This could be anything from water to oils. The specific heat, boiling point, and freezing points are all taken into consideration when choosing a HTF. The integrated compound parabolic concentrating (ICPC) evacuated tube collector reduces thermal heat loss, which makes the collection efficiency almost 60% (Henkel, pars.5). The collected rays can deliver about half of the available solar insulation to usable energy. The Solargenix Power Roof system is a solar energy collector that changes its angle throughout the...
